FAQS

Frequently Asked Questions

We advise initiating the first cleaning after the installation of a new DPF at 250,000 miles, followed by subsequent cleanings every 150,000 miles or annually thereafter. In the case of trucks or equipment that undergo frequent idling, we recommend more frequent cleaning to ensure the ongoing cleanliness of your aftertreatment system.

Utilizing our in-house DPF cleaning equipment and technology, we can ensure a turnaround time ranging between 16 and 24 hours.

Before proceeding with cleaning, we conduct pre-tests on the majority of DPFs (please be aware that not all DPFs can be tested due to varying shapes). These pre-tests involve assessing air restriction, weight, conducting light tests, and identifying any potential cracks in the DPF.

For a single pancake shape or a similar configuration, the cost is $350 each. If the DOC is cleaned together, the total cost is $500. We strongly recommend that our customers reach out to us via phone to receive the most accurate and competitive quote for their specific needs.
